Thanks for your input Tony.
Just to clarify my situation, I am not actually co-locating the APs,
just spreading more and more around our building. I need to keep
coverage of the whole building. Clearly, I am not using gain antenna,
they are all standard omni's.
It's a bit like the four-colour map-colouring problem - only now I
am working in 3 dimensions (3 storey building with APs on each level).
I'm going to try reducing the channel spacing to use channels 1, 5, 9 and 13.
I should get 18MHz of clear radio bandwidth between these channels, hopefully
enough to keep it all working at 11Mbps per AP simultaneously.
